(Arch) Linux freezes on second resume...

May 16 2017 by will
I run Archlinux on most of my workstations, including the trusty Lenovo t420 that I carry around. It’s been an amazing little tool, and remarkably functional for close to 6 years now. Try that with a freakin’ Macbook. Anyway, recently I noticed that it would occasionally freeze right after waking up from suspend to RAM, but only the second time I suspended it after a cold-boot. The first suspend/resume cycle would work just fine, but on the second resume it would wake up the display then immediately freeze, no mouse movement, no TTY switching, nothing.

pfSense -> influxdb metrics collection

UPDATE Oct 20, 2017 As pointed out in the comments below, most of this is no longer needed since the official release of the telegraf package for pfSense 2.4 and above. I’m still leaving it up for posterity. If any of the pfSense folks read this, some extra configuration options on the settings page for the plugin would be nice to see; but otherwise works like a charm. If you’re like me, a sexy looking dashboard is a difficult thing to look away from.

Make XenServer 7 do meaningful things

Update Jan 31, 2018 This is verified (by me, at least) to work on both the official XenServer 7.2, and with the experimental xcp-ng. I've also semi-automated the process with these Ansible bits for new hardware / pool upgrades. Don’t get me wrong, XenServer 7 is a huge improvement over previous versions, and still my product of choice for those that don’t want to pay a literal fortune for vmWare licensing.
